改良羟基磷灰石义眼台植入术临床观察

Prevention of exposure associated with orbital hydroxyapatite implant

目的:观察改良的羟基磷灰石义眼台植入术的疗效。方法:对32例改良的义眼台植入术,其中Ⅰ期18例,Ⅱ期14例,进行回顾性分析。结果:本组改良的羟基磷灰石义眼台植入术后,义眼活动度好,与健眼同步,无脱出、眼窝凹陷或上睑下垂;其中3例义眼台暴露,重新手术修补。结论:对严重的眼球破裂伤、无光感疼痛性眼球或萎缩眼球患者行改良的羟基磷灰石义眼台植入术,是一种较安全而有效的方法。

AIM： To evaluate the clinical effect of hydroxyapatite（HA） orbital implant. METHODS： Thirty-two cases with HA orbital implant performed in our hospital were observed. In these cases,18 cases of HA orbital implants were in stage Ⅰ, 14 cases were in stage Ⅱ. RESULTS：HA orbital implants were performed in 32 cases, failed in 3 patients. 29 patients underwent successful surgery without major complications. There was no implant extrusion or exposure in the series examination.No patient had the depression of orbit or ptosis. No patient had sympathetic ophthalmia during the follow-up. CONCLUSION：In strictly selected cases, HA orbital implant is a safe and effective method for patients with severe eyeball rupture, blind, painful or atrophic eye.
